Other than possibly writing a Phyton script and running it from a AGOL Notebook, I was wondering if anyone has any ideas on how to monitor for a lack of activity in a feed.
It can not be done in the RTA, as far as I know, as the presence of a Feed transaction is what triggers a flow through the RTA.
Just as an aside, I was troubleshooting a user complaint and found that the Cellular account had been suspended due to lack of payment (contact retired) so the sensor data supposedly coming through that connection was not.
If I could have generated an Alert on the lack of transactions I could have been proactive instead of reactive.
